The Sci-Tech Amateur Radio Society (STARS) at New England Sci-Tech (16 Tech Circle, Natick) and the Wellesley Amateur Radio Society will both participate in the worldwide Amateur Radio Field Day with their own family-friendly events open to the public on June 25-26.

• The STARS event in Natick event will be open to the public June 25, 2PM-5PM and June 26, 10AM-2PM. Sign up on the form on this page. STARS will offer educational demonstrations, maker activities, tours, soldering workshops, and telescope viewing (weather permitting). The Field Day will operate outside in vans and tents using auxiliary power to simulate emergency conditions, but the building will be open. You will not need a radio license to participate in the radio practice and contests, as you can operate with one of the club’s General or Extra class licensees as the control operator.

Newton families with students in ages 4-16 — who are interested in STEM and/or robotics (or think they may be!) — are invited to a free information session about First Lego League (FLL), on Wednesday, June 22, 7:30-8:00PM, hosted by Newton’s high school robotics team, the LigerBots. Parents, guardians, students, and potential mentors can learn about how the FLL season and competitions run, what is required to participate, and what students can gain from the experience. This Info Night will be held at Newton South High School. Sign up here.

FIRST Lego League (FLL) is an annual robotics competition in which teams of 2-10 students build a robot, solve engineering challenges, and learn in a friendly competition. FLL offers different divisions for ages 4-6, 6-10, and 9-16+.

Several students currently on the LigerBots started in robotics by participating in FLL, and the high-school team has been extremely generous in mentoring Newton FLL teams and hosting two major FLL competitions each year. The Info Night speakers will include past FLL participants, ready to share experiences and answer questions. They will provide information on how students can start their own teams — and how adult do not need backgrounds in engineering to be successful FLL coaches!

Boston’s Museum of Science will host a free, all-day forum — EmPowered by AI: Should We Engineer a More Sustainable City? — on June 26, 10AM-4PM.

No background knowledge of artificial intelligence is required. This program is supported by the Patrick J. McGovern Foundation, Toyota Research Institute, BNY Mellon, and The Boston Foundation.

As part of its Summer Thursdays evening events for ages 18+, Boston’s Museum of Science will host three films from the Woods Hole Film Festival at the museum’s Mugar Omni Theater:
